Rotary vane pumps

Rotary vane pumps

The one-stage pumps RE 2.5 are high-performance rotary vane pumps with extra compact design and low weight. They are the ideal solution for a wide range of laboratory and process applications that require low ultimate vacuum at medium gas flow rate. Typical applications are lyophilization, fine vacuum distillation and evacuation of small volumes, e.g., for utilization of µ-focus x-ray tubes or filling with pure gases.

Key Features
  • High flow rates even at vacuum levels approaching ultimate vacuum
  • Very good ultimate vacuum even with gas ballast
  • Vacuum-tight at switch-off; external anti-suckback valve not needed
  • Large oil volume: Long intervals between oil changes
  • Ease of maintenance due to telescopic design
  • Ultimate vacuum: 3 x 10-1 mbar
  • Ultimate vacuum with gas ballast: 8 x 10-1 mbar
  • Max. pumping speed 50 Hz: 2.3 m3/h
